mysql - SQL查询中的重复列名

Question

在两个具有相同列名的表上创建 VIEW 时，如何避免 MySQL 中的 dup 列名错误，如此处所示

CREATE VIEW db.VI_RegionCity AS SELECT
    Region.Name,
    City.Name
FROM
    db.Region Region,
    db.City City
WHERE
    Region.RegionCode = City.RegionCode



ERROR: Duplicate column name 'Name'

Answer 1

使用别名作为列名

CREATE VIEW db.VI_RegionCity AS SELECT
    Region.Name as Region_name,
    City.Name as City_name
...//rest of the query

Answer 2

CREATE VIEW db.VI_RegionCity AS SELECT
    Region.Name AS RegionName,
    City.Name AS CityName
FROM
    db.Region Region,
    db.City City
WHERE
    Region.RegionCode = City.RegionCode
